A new biologic “patch” that is activated by a person’s natural motion could be the key to fixing herniated disks in people’s backs, according to researchers at the Perelman School of Medicine at the University of Pennsylvania and the CMC VA Medical Center (CMCVAMC).

Combining years of work from many different projects, the “tension-activated repair patches” (TARPs) provide controlled release of an anti-inflammatory molecule called anakinra from microcapsules over time, which helped disks in a large animal model regain the tension they need to reverse herniation and prevent further degeneration. This pre-clinical research is detailed in a paper published in Science Translational Medicine.

“Currently there is no curative treatment for disk herniation, and the best thing out there ...

In connection with violent solar eruptions, large variations occur in electron density in the ionosphere over Greenland, which interferes with GPH navigation signals as well as flight and satellite communication. The figure (right) shows large electron density in red and small density in blue. This phenomenon gives rise to high electron speeds in the ionosphere, exceeding 1,000 metres per second (left) and resulting in violent energy bursts. For the first time ever, researchers from DTU have demonstrated the phenomenon which cannot yet be explained. (Illustration: DTU Space).

New research from DTU, JPL and University of New Brunswick shows that eruptions on the Sun’s surface not only send bursts of energetic particles into Earth’s atmosphere causing disturbances in our planet’s magnetic fi...
